Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed May 10,1905. Serial No. 260,010

To all whom it may concern:

Be it known that I, JAMEs J. FETZER, a citizen of the United States, residing at Columbiana, county of Oolumbiana, and State of Ohio, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full,

I wrench without the necessity of independent fastening means.

The invention will be hereinafter described, and particularly pointed out in the claims following.

In the accompanying drawings, which form part of this application, and whereon corresponding numerals of reference indicate the same parts in the several views, Figure 1 represents in perspective my invention applied to an ordinary nut-wrench. Fig. 2 is a perspective view of my invention detached; and Fig. 3 is also a perspective view similar to Fig. 2, but from the opposite point of observation.

Reference being had to the drawings and numerals thereon, 1 indicates a wrench-handle, 2 its outer fixed jaw, and 3 its inner ad- ,justable jaw, all of ordinary and well-known construction.

Upon the handle 1 adjacent to the fixed jaw 2, as shown cured my present invention, comprising spring side flanges 4 5, an intervening steel space-block 6, having a serrated working face 7, and a plain opposite or inner surface 8, the latter, by preference, slightly overlapped by the projecting edges of said flanges The spring side flange 4, differ- 4 and 5.

by Fig. 1, is detachably se-' ing from the flange 5, extends upward and terminates in a spring-hook or retaining member 9 for purposes which will now appear.

The use and operation of this invention may be briefly stated as follows: It being de sired to convert an ordinary nut or bolt Wrench into a pipe-wrench, this may be instantly accomplished by the use of my im proved unitary attachment, which is clearly shown by Figs. 2 and 3 of the drawings. This attachment is clipped into position upon handle 1 at a point intermediate of the jaws 2 and 3, the spring action of the upper portion-9 of the side flange 4 permitting of such instantaneous adjustment. Thereupon the attachment is slid longitudinally upon its supporting-handle 1 until the projecting side flanges 4 and 5 embrace the fixed wrench-jaw 2, as shown by Fig. 1. These flanges then cooperate with the upper spring-hook member 9 to snugly retain the attachment'in operative position against lateral movement or other accidental displacement regardless of the strains to which it may be subjected in the course of usage. Nevertheless the attachment may be instantly removed when desired by a reversal of the operation heretofore described, and obviously it may as well bev replaced in a reversed position or adjacent to the adjustable wrench-jaw 3, in which latter event the action of the wrench upon a pipe would be reversed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a wrench the combination with an auxiliary detachable j aw having a spring-acting retaining-hook, and side flanges adapted to partially embrace one main jaw of the wrench, substantially as described.

2. In a wrench the combination with an auxiliary detachable jaw having a spring-acting retaining-hook and projecting side flanges adapted to coact with said hook to prevent accidental displacement of said auxiliary jaw, substantially as described.

3.
